APPARATUS FOR DIVIDING LIQUIDS.V

Specification of Letters Patent.

Application filed April 4, 1914. Serial No. 829,648.

To all whom t may concern.'

Be it known that we, BERTRAND CHASE HINMAN, a citizen of the UnitedStates of America, and a resident of London, England, and ERNEST WILLIAMRonny, a subject of His Majesty the King of Great Britain, and aresident of South Voodford, Essex, England, have invented a certain newand useful Improvement in Apparatus for Dividing Liquids, of which thefollowing is a specification.

This invention relates to improved means for dividing flowing liquidsinto two or more streams having a constant volume irrespective ofvariations in the volume of flow and to means for varying the ratio ofsuch streams from time to time as may -be desired.

The accompanying drawings illustrate forms of apparatus by which thedesired result may be attained, although such forms may be modied tomeet varyinof circumstances without departing from the nature and scopeof the present invention.

In said drawings: Figure 1 is a plan of one form of apparatus, the coverand inlet pipe shown in Fig. 2 being omitted, the outer walls of t-hevessel being shown in section. Fig. 2 is a vertical transverse sectionof Fig. 1, Fig. 3 is a perspective view of a catchment cup, the topwalls of part thereof being shaded to show that they are represented aschisel edged. Fig. 4 is a plan of a modified form of apparatus, Fig. 5is a vertical transverse section of Fig. 4, F ig.V 6 is a verticalsection of another modified form of apparatus and Fig. 7 is an end viewof the brackets which carry catchment cups as hereinafter described oneof such cups being shown resting thereon.

As shown in said drawings, Figs. 1 to 3, a water supply l extendsthrough a cover 2 of .a tank 3 into a conical vessel l located withinthe tank. The vessel 4 the sides of which form a weir, is thickened nearthe edge to form a rim 5 which is rounded oft' at the top edge and isunder cut to form a sharp lower edge 6. 'Ihe weir is supported on lugs 7projecting from the side thereof and drilled and threaded to accommodatevertical set screws 8 which rest on brackets 9 bolted to the sides ofthe tank. Liquid is delivered through the pipe 1 into the vessel el andHows over the top thereof in an even Vfilm-like stream into the tank 3whence it is drawn olf through a pipe 10. In'order to insure that aneven stream will `ilow over the weir, that is to say, a stream having atany moment a uniform cross-section, it is necessary that the top of rim5 should be accurately disposed in al horizontal plane and this can beeasily effected by adjusting the screws 8. Also, owing to the fact thatthe delivery edge 6 of the rim 5 is lower than is supported on the cup.This tray has three side walls 17, 18, 19, the wall 17 being extendedlaterally. A slot 2O is provided in the extended portion of the wall 17and a stud bolt 21 passing through said slot is adapted to fiX the trayin the desired position. The catchment cup 11 is adapted to intercept apart of the stream of liquid flowing over the weir Vand the interceptingarea of the cup'can be varied by adjusting the tray or cover 16 to covermore or less of the cup. In order to prevent splashing of the liquid asit falls into the cup and to insure accurate division, the wall 18 ofthe tray and a l wall 22 of the cup are provided with chisel upperedges. Thus it will be seen that a part (which may be varied) of thetotal stream is divided off by the catchment cup and that such parthears a constant ratio to the total stream flowing over the weir.

Referring now to Figs. 4: and 5, which illustrate a modification of theapparatus, a hollow cone shaped casting la is mounted to standvertically in a tank 3 and communicates through a hole in the bottom ofthe tank with a liquid supply pipe la. Secured to the upper end of thecasting 4a is a curved sheet metal rim 5a. As shown the curvature isapproximately semi-circular in cross section. The liquid flows upthrough the casting 4f* and over the rim 5a into the tank 3.

In order to prevent the liquid from surging Y or splashing and to insurea smooth stream a perforated baffle plate 23 is disposed at the mouth ofthe casting 4a. The external edge 6@L of the rim 5a is lower than theupper curved surface thereof and this presents the advantageous Vfeaturethat the liquid is guided in a manner most suitable to obtain an evenstream, and that there is space between the delivering edge and theconical upcast portion for the adjustment` of the catchment cups. Inorder to provide for the accurate adjustment of the rim a in ahorizontal plane the casting 4a is mounted on a compressible vpackingring 24, and four radial screw rods 25, 26, 27 and 28, are providedwhich latter are anchored to the casting- 4a and are adjustably securedto the walls of the tank 3 as by nuts 29. By this means the accurateleveling up of the rim may be eiected. rlhe parts thus far describedvirtually constitute a weir, the liquid owing into the tank 3 whence itescapes by way of the hole 30. Attached to the wall of the casting 4a byScrew bolts or other well known means not shown is a bracket 31 on whicha catchment cup or receptacle 11a is justment beneath the weir. rlheadjustment of the position of the cup 4or receptacle 11a is usuallyeected by hand and such cup can be held in the desired position by meansof a set screw 52 passing through the yoke 53 attached to the cup andembracing y the bracket as most-clearly seen in Fig. 7 Owing to the formof the cup 1la whichhas sides that are approximately radial to the weir,a greater or less proportion of the total stream will fall or flow intothe cup as the latter is moved toward or from the center of the weir. Itwill be seen that the proportion of liquid that enters the cup 11a bearsthe same relation to the total volume of the stream as the width of thecup presented to the stream bears to the circumference of the rim 5awhatever the position of the cup may be. At right angles to the bracket31 in the construction shown is a second bracket 32 attached by anysuitable means (not shown) to the wall of the casting 4 and on which asmaller catchment cup l1b is mounted, adjusted and held in a similarmanner to cup 11a, it being illustrated here as another form of cup andto show the possibility of selecting two streams, havingdifferent ratiosto the main stream. The cup 11b has a portion 34 which has side walls onapproximately radial lines to the weir and is adapted to enter beneaththe stream, a chamber 35 having V shaped notches 36 in the side wallsthereof, and a third or final chamber 37 divided from the chamber 35 bya partition 38,\in which 'is another V shaped notch 39. The liquid iowsfrom the rim 5a into the portion 34 and chamber 35 where it issub-divided, one portion passing through the notches `36 into the tankyand the other portion passing through the notch "39 in the partition 38into `the chamber 37 where it is drawn on by way from the Weir aspreviously described. Thesubdivision of the liquid eected in the cuplmay be varied to suit the convenience of the case by increasingOr-.decreasmg the number or capacity of the `notches 36y and 39 in thesides of the chamber 35 and the partition 38, provided always that theirapices are Vin the same horizontal plane. The catchment cups may takevarious shapes provided that they are adapted to extend along a greateror less distance ofthe stream as they are moved to or from the latter.

Referring to Fig. 6 whichiillustrates diagrammatically anothermcdiiiedform` of the apparatus, the casting `4a hasa number of inwardlyprojecting arms 43 'which support the lower end of a vertical spindle44, the

upper end of which 'is' supported by a spider.

bracket 45. On the Ispindle 44 is a sleeve 46 which is free t'o rotatethereon and which carries two arms 47, 48. The arm 47 supports acatchment `cup or receptacle 1lc which may have a tray or cover asdescribed with reference to Figs. 1 3, and the arm 48 carries a numberofvanes 49 inclined at such an angle to the 'stream owing over the rim5L that they are causedto rotate around the rim and with them thecatch-1 ment cup 11G. The catchment cup 11c has a spout or pipe 50 thatextends over a trough 51. It wi lbe' seen that by-this construction thewater is drawn or collected from all points of the circumferenceof therim 5a soA iio l. In apparatus of the kind described the flowing liquidto assume an even film-like.

stream, a catchment cup adapted to intercept part of said stream andmeans whereby the intercepting area of the cup presented to the streamcan be varied.
